Marine Geochemistry


Book Description

Since 1980 a considerable amount of scientific research dealing with geochemical processes in marine sediments has been carried out. This textbook summarizes the state-of-the-art in this field of research providing a complete representation of the subject and including the most recent findings. The topics covered include the examination of sedimentological and physical properties of the sedimentary solid phase. A new chapter describes properties, occurrence and formation of gas hydrates in marine sediments. The textbook ends with a chapter on model conceptions and computer models to quantify processes of early diagenesis.

Climate Change and Island and Coastal Vulnerability


Book Description

"Climate Change and Island and Coastal Vulnerability” is the outcome of a selection of peer reviewed edited papers presented at the International Workshop on Climate Change and Island Vulnerability (IWCCI) held at Kadmat Island, Lakshadweep, India in October 2010. Marine and coastal biodiversity, sea level rise vulnerability, fisheries, climate change impact on livelihood options, water and sanitation in island ecosystem and mitigation, adaptation and governance are the focal themes. The basic concept conveyed in the book is that biodiversity of islands is to be protected as a natural mechanism to mitigate climate change. Probability recurrence of mass coral bleaching and the management of coral reefs and their future protection are discussed in this book. Marine productivity and climate change for the last ten thousand years in the Arabian Sea have been examined with core records. Green technology is suggested as an important tool for mitigation and adaptation programmes in climate change. Measures taken to project biomass utilisation of islands as an energy source is delineated. Climate change may pose a potential threat on human health. Improved sanitation packages and models that are cost effective and environment-friendly for islands are uniquely presented in this book.




Geomorphology and Physical Oceanography of the Lakshadweep Coral Islands in the Indian Ocean


Book Description

The Lakshadweep islands are a group of 36 coral islands in the Indian Ocean. These small islands are unique for their aquatic bio-diversity and vast blue lagoons. This book presents the results of studies done by the authors during the period 1990 to 2009 that address the beach morphology, hydrodynamics, energy resources and management options with special reference to the issue of both natural and anthropogenic coastal erosion. The relatively low island elevation makes the islands more susceptible to high-wave attack and coastal flooding during adverse weather conditions. The islands are also prone to risks from episodic events like cyclones and deep depressions. This highlights the need for a comprehensive study of the wave, climate and coastal processes at work during different seasons to delineate the factors responsible for shoreline changes and also to identify the locations that need protection and the management options. This book will serve as a guide to researchers, scholars and students who are interested in the coastal processes of coral islands.




Urban Hydrology, Watershed Management and Socio-Economic Aspects


Book Description

The book brings together high-quality research articles on advanced hydrological analysis, advanced computational methods, and the ecological and sociological aspects of urban watershed management under one umbrella. The rapid pace of urbanization, not accompanied by any farsighted, holistic plan, has reduced many cities in the developing world into multi-hazard areas. The most perceptible consequence of urbanization is the change in land-use and land cover, which in turn impacts hydrological systems. Accordingly, scientific studies on urban hydrology with due emphasis on ecological and sociological aspects under changing climate are vital to the appropriate design of urban landscapes and civil infrastructure works. This book addresses precisely these issues, offering a useful guide for environmentalists, hydrologists, and a broad range of socio-economic scientists exploring the environmental vulnerabilities arising from urbanization.




Holocene Climate Change and Environment


Book Description

Holocene Climate Change and Environment presents detailed, diverse case studies from a range of environmental and geological regions on the Indian subcontinent which occupies the central part of the monsoon domain. This book examines Holocene events at different time intervals based on a new, high-resolution, multi-proxy records (pollen, spores, NPP, diatoms, grain size characteristics, total organic carbon, carbon/nitrogen ratio, stable isotopes) and other physical tools from all regions of India. It also covers new facilities in chronological study and luminescence dating, which have added a new dimension toward understanding the Holocene glacial retreats evolution of coastal landforms, landscape dynamics and human evolution. Each chapter is presented with a unified structure for ease of access and application, including an introduction, geographic details, field work and sampling techniques, methods, results and discussion. This detailed examination of such an important region provides key insights in climate modeling and global prediction systems. Provides data and research from environmentally and geologically diverse regions across the Indian subcontinent Presents an integrated and interdisciplinary approach, including considerations of human impacts Features detailed case studies that include methods and data, allowing for applications related to research and global modeling







The Indian Ocean Tsunami


Book Description

The Indian Ocean tsunami of December 2004 is considered to have been one of the worst natural disasters in history, affecting twelve countries, from Indonesia to Somalia. 175,000 people are believed to have lost their lives, almost 50,000 were registered as missing and 1.7 million people were displaced. As well as this horrendous toll on human life
